Treat the contents of the XML as a string, and just search the content string for the one you are looking for.

public bool FileContainsString(string filePath, string searchString)
{
    string fileContents;
    using(FileStream file = new FileStream(filePath, FileMode.Open))
    using(StreamReader reader = new StreamReader(reader))
    {
        fileContents = reader.ReadToEnd();
    }

    return fileContents.Contains(searchString);
}

This code was not tested

If you want a case-insensitive search for the string, replace 

    return fileContents.Contains(searchString);

with

    return fileContents.IndexOf(searchString, StringComparison.OrdinalIgnoreCase) > -1;

XmlDocument doc;
bool contains = doc.InnerXml.IndexOf("Your text") != -1

should do the trick, but it will find the text even if it is contained in a tag, if you want just to check for plain text use:

XmlDocument doc;
    bool contains = doc.InnerText.IndexOf("Your text") != -1
